The MY-A20 is a second-generation, benchtop, compact-size fully automatic IHC stainer with a staining capacity of 20 slides. Each of the staining positions is controlled independently with the highest possible precision. Dewaxing, antigen retrieving, and DAB mixing are performed as a part of the routine staining procedure and do not require additional devices. Manual addition of primary antibodies is possible while the stainer software enables customization.
